Adwords tip
I’ve found Today that limiting your Adwords “region” to your postcode + area in some radius doesn’t exactly work the way you think - Google seems to have hard time accurately mapping the IP addresses to physical locations, my region was “ME15 8LJ + 150 miles” and my ad was almost not showing anywhere - after changing that to England the results are dramatically different, one of my campaigns suddenly has <b>100 times</b> more impressions, and the other one - <b>30 times</b>.
I don’t think it’s because the South East England being scarcely populated 
So - if you want to reach anyone with your ads - aim for the whole country, otherwise you’ll miss out on your neighbours.
Another interesting thing seems to be that the ads are reacting to “keywords” and “phrases”, but when one inputs your “keyword” and appends the query with other words - the Adword doesn’t seem to show - I’m not sure if that’s appropriate, but that’s the way it seems to work.
I’ll post my further findings when I gather more experience with that system.
And by the way - Google doesn’t have any problems charging my account for clicks, one thing less to worry about
